Two enigmatic, poorly preserved specimens of mammalian upper molars have been recovered from the Eric the Red West locality in Victoria, Australia. They are two of the three known specimens of mammalian upper molars from the Mesozoic of Australia. The two are quite different from one another. One is likely to be a tribosphenic mammal, the other may have a distant relationship to the monotreme or haramyid Kollikodon. Thomas H. Rich [], Timothy Ziegler [], Peter Trusler [], Timothy F.
